Adds two new plot methods and health expenses

Two new graphs created, discrete, where all discretionary expenses are
plotted, and average, for the yearly average. This later one will be
moved to report form.
Health expenses separated from required. Commute moved from fixed to
required expenses.
New by_month_and_category functions added to transactions.py.
